    Although vitamin K in green leafy vegetables affects the action of warfarin (Coumadin), green leafy vegetables should not be eliminated from a diet. To avoid a yo-yo effect in the action of warfarin, healthcare providers suggest that consumption of green leafy vegetables should not vary widely while on warfarin treatment.
